The composition of the glue

The chemical makeup of BF glue can vary depending on the particular brand. Every series’ means are produced in compliance with GOST 12172-74.

The specialist will be able to determine that polyvinylButiral (also known as polyvinilalcetal) is the primary ingredient by deciphering the name, glue botiralphenol. The percentage of the primary ingredient in dry matter—which provides the material’s elasticity—is shown by the figure that follows the BF brand.

The quantity of these components varies amongst BF types; the more of them there are, the more flexible the dry glue layer is, but the weaker it is. The adhesive includes:

  • phenol -formaldehyde or phenolivinyl acetate resin;
  • ethyl alcohol (solvent).

The manufacturer may choose to substitute acetone or chloroform for the final part. Only alcohol can be used to dissolve medical glue BF-6.

All of the means appear to be dense mixtures of reddish, brown, and yellowish colors. The adhesives pose a fire risk.

The history of origin

The invention of the product occurred in 1946, right after the war. The first was the glue BF-2, which was created by g. G. Petrov, a chemical scientist who also unlocked the plastic mass of carbolite. In 1950, medical glue was created, and surgeon L. Schoolboy was the first to suggest possible applications for it.

Areas of application and characteristics

The characteristics, properties, and technical details of materials vary based on the specific brand. Adhesives are commonly used in daily life, however it is not advised to use them for adhering dishes because they contain several toxic ingredients (BF-19 excepted).

Considered universal, many BF adhesives are capable of adhering to a wide range of materials. Although BF-2 and BF-4 adhesives have different applications, they are comparable in terms of heat and chemical resistance. Alternative methods are far less common and are not as widely used.


The adhesive composition is meant to be used for adhering static hard products that remain in place while in use, per the usage instructions. For gluing plastic, ceramics, metal, wood, glass, and marble, BF-2 works well. In the past, it was used to fix speakers, microphones, and other acoustic devices. The tool can be used for restoration work, varnishing, and impregnation of certain materials.

Glue’s heat resistance reaches +180 degrees and it enables the creation of a low-elastic seam following hot polymerization. When heated to +60… +80 degrees, the composition offers a tool for resistance in an acidic environment. The characteristics and key elements of the material are as follows:

  • viscosity according to the viscometer ZV-1 at a temperature of +20 degrees-30-60 C;
  • The share of the dry balance is 14 – 17 %;
  • The strength of the connection strength at a shift at a temperature of +20 degrees is 19.6 MPa (kgf/sq. cm);
  • Bending of the film after hardening – 3 mm.

When glue is stored below freezing temperatures, it may become more viscous. It needs to be kept at room temperature for three days before using. BF-2 is resistant to the effects of alcohol, alkali, acetone, acids, water, mold, and oil, gasoline, and kerosene.


Skin, glass, metal, wood, and other materials in products that are prone to flexion and vibration can all be adhered to with this composition. It works well on copper, steel, fiberglass, and aluminum-magnesium alloys. The product is capable of joining metals and non-metals.

BF-4 glue can be used at low temperatures and is resistant to the action of alkalis. The material’s ability to withstand the effects of salt fog and its electrical insulating qualities make it unique.

The means’ primary technical specifications are:

  • viscosity according to the viscometer ZV-1 at a temperature of +20 degrees-30-60 C;
  • The proportion of the dry residue is 10 – 13 %;
  • The strength of the connection strength at a shift at a temperature of +20 degrees is 19.6 MPa (kgf/sq. cm);
  • Bending of the film after hardening – 1 mm.

The BF-4 produces the strongest seams when it hardens at +160 to +175 degrees, making the hot method of application the most preferred. It is not recommended to use the tool above the upper limit of its range as this will weaken it. Lower the number of blows the indicator makes on the adhered surface.

BF-2N and BF-4N

Ferrous metal components and products are assembled using adhesives. After drying, the operating temperature ranges from -60 to +80 degrees. There is no difference between the BF-2N and BF-4N funds’ primary technical specifications:

  • viscosity according to the viscometer ZV-1 at a temperature of +20 degrees-30-60 C;
  • The strength of the connection strength at a shift at a temperature of +20 degrees is 19.6 MPa (kgf/sq. cm);
  • The share of the dry balance is 14 – 17 %.


Metals can be adhered to non-metallic products using BF-88 adhesive. For what other purpose is glue used? Connecting fabrics, wood, glass, ceramics, skin, plastic, and different synthetic materials calls for the use of this product. Since glue can be used for a wide range of everyday repairs, it is known as the universal adhesive.

This tool is made of a combination of phenol-formaldehyde resin, ethylacetate, nephras, and chloroprene rubber. Sediment may fall from the viscous, gray-green or beige mass. The product is made in 25–50 liter industrial containers as well as tubes.


For hot gluing glass, ceramics, metals, and wood, use BF-19 glue. You can glue rubber, cardboard, paper, plastic, and fabric using the cold method. An iron can be used to glue the fabric.

Feature: extremely toxic. Dishes and other household items cannot be fastened for use as medical equipment.

Then let the product dissolve? Acetone can be used for this purpose, just like it can with other BF adhesives.


A medicinal substance, BF-6 material is based on bakelite varnish. It is frequently used to treat wounds and abrasions with antiseptics and to form a film over them.

In dentistry, postoperative seams are sealed with glue. Can be used by anyone, with the exception of infants and people with component allergies.

Instructions for use BF-2 and BF-4

The following is how BF-4 glue is used: The surfaces must first be properly prepped (closed, cleaned, and degreased).

The technology used in the hot method of gluing is as follows:

  • apply an even layer of glue to the details;
  • leave for an hour;
  • Next, squeeze the parts with each other, hold at a temperature of +150 … +170 degrees 40 minutes;
  • Gradually cool the product to room temperature.

The next step is the procedure if tissue gluing is used. After squeezing and lightly moistening the fabric with water, a thin layer is applied, and it is left to dry for an hour. After that, the products are joined and heated ironed. How much glue dries when applied using a hot method? Products are usable after five hours because so much is required for the last drying.

It’s simpler to use the cold method. After 20 minutes of applying the glue, press the products together with a second layer after a few minutes. They become usable after a day.

After parts are stripped and degreased, BF-2 glue is applied. Ten minutes after applying the first layer, a brush is used to apply the second. The products are heated to between +130 and +140 degrees for 60 minutes when using the hot method. In the cold method, the component is placed in a ventilated room for a day after being compressed in a vice for 20 minutes.

How to remove glue glue

You could easily remove the material if it ended up in an unaccounted-for location and contaminated your skin or clothing. The sponges are moistened with alcohol or vodka to remove the glue. The base needs to be processed once more to get rid of any leftover glue after 20 minutes.

With a cotton circle and a solvent, you can remove the product from the fabric. Previously, you should examine the product’s back to see if the fabric has any flows or bleached areas.
